DETAILED DESCRIPTION

While the present disclosure is described with reference to several illustrative embodiments described herein, it should be clear that the present disclosure should not be limited to such embodiments. Therefore, the description of the embodiments provided herein is illustrative of the present disclosure and should not limit the scope of the disclosure as claimed. In addition, while the following description references an extending level apparatus in an I-beam configuration, it will be appreciated that the disclosure may be used with any kind of orientation measuring apparatus including a non-I-beam level configuration, such as box structures.

Briefly described, a method and an apparatus are disclosed to measure the orientation of a work surface. This disclosure details a level apparatus having a body, a slider, and one or more orientation measuring device such as a spirit bubble vial. The slider is coupled with the body by fitting within a slide channel of the body. By sliding the slider in and out between a fully contracted state (shortest working length of the level apparatus) and a fully extended state (longest working length of the level apparatus), or at any distance between these two states, the length of the level apparatus can be changed to accommodate a work surface, to be orientation-measured, that is longer than the length of the level when in the fully contracted state. The body includes a planar surface on one side that comes in contact with the work surface. A non-coplanar contact member is coupled with an endcap coupled with slider. Both the planar surface and the non-coplanar contact member rest on the work surface to be orientation-measured. The non-coplanar contact member includes a tip for resting on the work surface and this tip is coplanar with the planar surface. That is, the tip lies in the same plane as the planar surface of the level body.

The extending feature of the level apparatus is provided by having a main body for the level apparatus with a frame including a slide channel housing, a slider coupled to an endcap forming the sliding extending part of the level apparatus. The orientation measuring devices are coupled to the main body in an embodiment of this disclosure, where the non-coplanar contact point of the level apparatus is coupled to the endcap at the end of the slider.

A level apparatus is commonly used in construction business, and most often masons and framers use both a short and a long level apparatus when laying bricks, framing a structure, or other similar processes. The short level is used for controlling levelness of the individual brick laying and the longer level apparatus is used for longer surfaces, and also, when vertically used with respect to the structure, to make sure the raised structure is plumb. It is useful to have a single extendable level apparatus that in a contracted configuration can work as a short level apparatus and in an extended configuration can be used as a long level apparatus. Furthermore, the most common level apparatus resembles an I-shaped structure with the flanges used as surfaces to rest on a work surface to be orientation measured with spirit bubble vials placed in the web of the level apparatus. Usually, the work surfaces are not perfect planar surfaces with perfect surface finishes. Bumps on work surfaces may introduce error in orientation measurement of the work surface to decide if the work surface is adequately level and/or plumb. A level apparatus that provides a non-coplanar contact member at one end of the level apparatus can overcome the issue with imperfect work surface finish, by resting on the work surface and between any bumps that may be on the work surface.

In some embodiments of present disclosure, a level apparatus includes a body, a slider coupled with the body to slide parallel with respect to the body to extend a length of the level apparatus. The level apparatus further includes a planar base surface on a side of the body to allow the level apparatus to rest on a work surface the orientation of which is to be measured, and a non-coplanar contact member at an endcap of the slider to rest on the work surface when the slider is in an extended position, wherein a tip of the non-coplanar contact member is coplanar with the planar base surface.

The level apparatus further includes an orientation measuring device, wherein the orientation measuring device includes a bubble vial, a circular vial, an electronic orientation measuring device, a piezoelectric based orientation measuring device, or a combination thereof.

The non-coplanar contact member of the level apparatus includes a semi sphere, or alternatively a plurality of semi spheres coupled to the endcap about equally distanced from each other forming a matrix, and wherein the tips of the non-coplanar semi spheres are coplanar with the planar base surface.

When the endcap of the apparatus extends away from the body a length of the level apparatus increases, and with the endcap not extended away from the body the level apparatus is in a contracted configuration or state.

In some other embodiments of present disclosure an orientation measuring assembly includes an I-beam shaped body, wherein the I-beam shaped body includes a web and an upper flange forming a planar base surface of the body to rest on a work surface the orientation of which is to be measured.

The body of the orientation measuring assembly further includes a slide channel, wherein a slider is coupled with the body via the slide channel, and the slider slides parallel with respect to the body to extend a length of the level apparatus. An endcap is coupled to a free end of the slider, and a non-coplanar contact member at the endcap of the slider rests on the work surface when the slider is in an extended position, wherein a tip of the non-coplanar contact member resting on the work surface is coplanar with the planar base surface.

The orientation measuring assembly further includes an orientation measuring device, wherein the orientation measuring device comprises a bubble vial, a circular vial, an electronic orientation measuring device, a piezoelectric based orientation measuring device, or a combination thereof.

The non-coplanar contact member of the orientation measuring assembly comprise a semi sphere, alternatively the non-coplanar contact member comprise a plurality of semi spheres coupled to the endcap about equally distanced from each other forming a matrix, wherein the tips of the non-coplanar semi spheres are coplanar with the planar base surface.

The endcap of the orientation measuring assembly extends away from the body increasing a length of the orientation measuring assembly; and with the endcap not extended away from the body the orientation measuring assembly is in a contracted configuration.

In some other embodiments of present disclosure a method for using a level apparatus includes sliding a slider coupled to an endcap through a slide channel of a body of the level apparatus, extending a length of the level apparatus to accommodate a length of a work surface which is to be orientation measured. The method of use of the level apparatus further includes resting a base surface of the body on the work surface, and further resting a non-coplanar contact member coupled to the endcap on the work surface, and making the orientation measurement of the work surface using an orientation measuring device coupled to the body. The orientation measuring device of the level apparatus includes a bubble vial, a circular vial, an electronic orientation measuring device, a piezoelectric based orientation measuring device, or a combination thereof.

In the method of use of the level device, the non-coplanar contact member includes a semi sphere coupled to the endcap, and a tip of the non-coplanar semi sphere is coplanar with the base surface. Alternatively, the non-coplanar contact member includes a plurality of semi spheres coupled to the endcap, wherein the plurality of semi spheres coupled to the endcap are spaced about equal distance from each other forming a matrix pattern; and wherein the tips of the non-coplanar semi spheres are coplanar with the planar base surface.

FIG. 1 shows an example level apparatus used for measuring orientation of a work surface. The illustration shows a contracted level apparatus 100 with a body 102 in an I beam general configuration showing a web 101 and as an upper flange of the I beam a planar base surface 103 for resting on a work surface to be orientation measured. Illustration further shows an orientation measuring device of a bubble vial 104 and circular vials 105 and 106. Even though not shown in FIG. 1, other orientation measuring devices such as an electronic orientation measuring device, and/or a piezoelectric based orientation measuring device may be coupled to the level apparatus 100. The orientation measuring devices can be coupled to the level apparatus 100 via glue, press fit, screwed in, welding, or other fastening techniques. FIG. 1 further shows an aperture 107 that can be used for a hanging rope for hanging the level apparatus 100 at one end, and an end cap 108 at the other end of the level apparatus 100. Furthermore, a non-coplanar contact member 109 a is shown coupled to the endcap 108.

The non-coplanar contact member 109 a coupling to the endcap 108 can be accomplished in different configurations. In one configuration where the non-coplanar member 109 a is initially not contiguous with the endcap 108, the two structures may be joined together using glue, press fit, screwed in, welding, or other fastening techniques. In an alternative configuration where the non-coplanar member 109 a is from the beginning contiguous with the endcap 108 the non-coplanar member 109 a and endcap 108 may be machined from the same block of material, where the machining may be through cutting the material, chemical etching, wire EDM (electro discharge machining), three dimensional (3D) printing of a structure including the non-coplanar member 109 a and the endcap 108, injection molding including plastic injection molding, casting, stamping, or other material forming techniques.

A contracted level apparatus 100 as shown in FIG. 1 is used to measure orientation of a work surface. Alternative methods for measuring orientation of a work surface may be by using a single elongated vial containing an air bubble captured in liquid; a visual laser beam providing a straight line of light for visual comparison with the work surface; or a level apparatus 100 which is based on a box cross section structure as opposed to an I-Beam cross section structure.

In FIG. 1, the planar base surface 103 of the body 102 and the non-coplanar contact member 109 a coupled to the endcap 108 are placed on the work surface, and an orientation of the work surface including its levelness and/or plumbness is then measured using the orientation measuring device bubble vial 104 and circular vials 105 and 106. An alternative method for measuring plumbness of a wall can be accomplished via visually comparing the surface of the wall with a stretched string forming a plumb line with a small weight (plumb bob or plummet) attached to a free end of the string with the other end of the string held fixed above ground. The rigidity of a level device allows smoothing uneven surfaces by the level's edge caused by, for examples, bricks that are not perfectly lined up or other debris and broken corners that make the work surface not even or smooth. This cannot be done by a plumb bob.

In various embodiments, the non-coplanar contact member 109 a, may be implemented in a number configurations, including one or more conical members, one or more semi-spherical members, one or more pyramid-shaped members, one or more cylindrical members, or one or more non-coplanar contact members having any other shape that satisfies the definition of a non-coplanar surface.

Illustration shows a front view of the extended level apparatus 200, wherein a web 101 of the I Beam channel of the body 102 along with a base surface 103 of the body 102 are identified. Further, a slide channel 201 with a lower rail 201 a and an upper rail 201 b of the body 102 and a coupled slider 110 in an extended configuration is shown. The endcap 108 coupled to the slider 110 and the non-coplanar contact member 109 a coupled to the endcap 108 are also illustrated. Slider 110 extends away from the body 102 by sliding through the slide channel 201, distancing the endcap 108 from the body 102 increasing the length of the level apparatus 100.

The endcap 108 coupling to the slider 110 can be accomplished in different configurations. In one configuration where the endcap 108 is initially not contiguous with the slider 110, the two structure may be joined together using glue, press fit, screwed in, welding, or other fastening techniques. In an alternative configuration where the endcap 108 is from the beginning contiguous with the slider 110 the endcap 108 and slider 110 may be machined from the same block of material, where the machining may be through cutting the material, chemical etching, wire EDM (electro discharge machining), three-dimensional 3D printing of a structure including the endcap 108 and slider 110, injection molding including plastic injection molding, casting, stamping, or other material forming techniques.
